Modeling the stress-strain state of the V95/SiC aluminum alloy matrix composite under uniaxial loading

In the paper we develop a computational model of plastic deformation of an aluminum matrix composite. The composite is produced by sintering, and it has a cellular microstructure. SiC reinforcement particles form a stratum along the pellet boundaries of the V95 (analogous to 7075) aluminum alloy. The effective properties of the plastic flow of the stratum material are obtained by the rule of mixtures, depending on the volume fractions of the aluminum alloy and the reinforcement particles in the composite material. The feasibility of the model is demonstrated on the example of numerical simulation of the micro- and macroscopic stress-strain state of the composite under uniaxial tensile and compressive loading conditions.
